Deploying to Fly.io

Fly.io’s main interface is a command-line tool called flyctl, which we can install with the following:

• iwr https://fly.io/install.ps1 -useb | iex on Windows PowerShell
• curl -L https://fly.io/install.sh | sh on Linux and macOS
• You can also use brew install flyctl on macOS too

Signing up with Fly.io is easy: issue the flyctl auth signup command. We recommend connecting your GitHub account, as you will need it later.

We can now deploy to Fly.io by executing flyctl launch in our current working directory (make sure there are no fly.toml files) and answering the following questions:

$ flyctl launch
